Frenkel-Kontorova Model
The Frenkel-Kontorova model is a
harmonic chain (mimic a layer of atoms)
in a spatially periodic potential (mimic the substrate).
The chain is driven by a constant
force and which is damped
by a velocity-proportional damping
(emitting waves into the substrate).
The equations of motion:
Boundary conditions:
- periodic:
